ennabler
One who inserts nablas ('del' signs, ∇) into documents, enabling successful vector calculus notation.
I couldn't find the nabla among the "Special Characters" (or the code for it, in LaTeX), but now I have, so I'm proud to be an ennabler.
crwth
The crwth (rhymes with tooth) is an archaic stringed musical instrument, associated particularly with Wales, although once played widely in Europe. One of only a few English words without a vowel (although the "w" serves as a vowel sound). Other vowelless Scrabble words (some of them dubious, in my opinion): HM(M), MM, SH(H), BRR(R), CWM(S), NTH, PH(PH)T, TSK(TSK)(S), PFFT, PSST.
